A polypectomy device and method which includes a snare cable (7), a fixed jaw (5) and moveable jaw (6). The snare cable is routed through both the fixed jaw and the moveable jaw. The snare cable forms a hoop for encircling the polyp. Shortening the snare cable positions the jaws about the base of the polyp and further shortening the cable closes the jaws. The fixed jaw includes a heating element (17) which cauterizes the base of the polyp. The closing of the jaws and the heating of the heating element cuts and seals the polyp.
La présente invention concerne un dispositif et un procédé de polypectomie comportant un câble à collet (7), un mors fixe (5) et un mors mobile (6). Le câble à collet est passé à travers le mors fixe ainsi qu'à travers le mors mobile. Le câble à collet forme une boucle pour entourer la polype. Le raccourcissement du câble à collet positionne les mors autour de la base de la polype et un nouveau raccourcissement du câble entraîne la fermeture des mors. Le mors mobile comporte un élément chauffant (17) qui cautérise la base de la polype. La fermeture des mors et le chauffage de l'élément chauffant coupe et obture la polype.
